Abstract

L'invention concerne un châssis d'écran permettant le montage de l'écran sur un afficheur à projection par transparence. Ce châssis est produit à partir de profilés et de supports d'angle. Les profilés et les supports d'angle sont assemblés de manière à former un châssis mince permettant de maintenir l'écran sur le boîtier de l'afficheur. Ce châssis d'écran forme une bordure d'environ 11, 5 mm autour de l'écran. Il est monté sur l'avant d'un boîtier d'afficheur de telle manière que l'écran s'avance à l'extérieur du boîtier, sur l'avant de ce dernier.
